CASING WAGON.

Applicd'titnfiled February 16, 1922; Serial No. 536,881.

This invention relates to casing wagons which are used around earth boringriggings for hauling well casings and other heavy, ap-

paratus from one point to another around the rigs.

Casing wagons as now used are nothing more than small two-wheeled trucks having handles thereon, by means of which they may be hauled about, and on which are special means for supporting or engaging sections of well casing. They are used in pairs, the front wagon being different from the back one. As heretofore constructed, the front wagon had a vertical threaded post therein which could be raised or lowered by turning it, and at the top of which was a prong in which one end of a section of casing could rest. The rear wagon,which is entirely separate and independent of the front wagon, had a vertical post at the front thereof on which the rear end of the section of casing being moved was hung. The front wagon had forwardly extending handles and the rear one rearwardly extending handles. NVhen the casing was supported on the two wagons, the rear one could be pushed while the front one was pulled and guided.

There are several difficulties with the wagons now in use. They are too heavy and are liable to break. Frequently, one of the wagons of a pair will break and cannot be repaired except at a shop. The driller may have an odd wagon to substitute or the odd wagon may be one that is similar to the good remaining Wagon of the pair. That is, he may have two front wagons and no rear wagon, or vice versa. Another inconvenience is that the vertical post on the rear wagon is of fixed height, and while suitable for casings of small diameter, are invariably too short for larger casings and the end of the larger casings will accordingly contact with the ground or the wheels of the wagon.

The present invention has forits'principal object to provide a wagon having interchangeable parts, so that it may be used at the front or rear end of the casing, or merely as a fiat topped vehicle for hauling heavy articles other than casings. Another im portant object is the provision of a vertically adjustable post for use on the wagon when it is at the rear of the casing. Other objects are to provide a wagon of this kind which may be formed as an integral casting and which will be stronger and lighter thancasing wagons heretofore, made.

PATENT.'OFF-VICEQ My invention may be readily understood byreferenee tothe accompanying drawings,

in which:

Fig. 1 1s a top plan view of a wagon constructed in accordance with my invention;

Fig. 2 is a longitudinal vertical section.

therethrough on line IIII;

Fig. 3 is a transverse section on line IIIIII of Fig. 2;

Fig. 4: is an end view; and

Fig. 5 shows the manner in which the wagons are used.

In the drawings, the body of the wagon M has been shown as an integral cast steel structure. It includes a flat platform 5 having a depending transverse vertical rib or web 6 thereon which terminatesin an enlarged portion 7. On each end of the enlarged portion 7 are integral axles or studs 8. Formed on the under side of the platform is a boss 9 having a threaded opening therethrough. Integral strengthening webs,

are indicated at 10.

The rear end of. the platform is extended beyond the web 6 and the corners thereof are cutaway, so that an extension of reduced width is provided. The rearwardly extending portion is designated as 11 and has an elongated opening 12 therethrough. At each side of, theopening and under the platform are integral parallel depending webs 13. ,Thesewebs are joined at the extreme rear end by a cross web 14 having an inclined serrated inner face 15. This portion 1 may be cast integral with the wagon body or formed separately therefrom and secured in place by means of transverse bolts or rivets 16 which extendthrough plates or .webs13 and member 14. Vertical bracing webs may be provided at each side of the platform, as indicated at 5.

A vertical threadedfpost 17 having a prong 18 at its upper end may be screwed into the threaded opening" in the forward part of the body when the wagon is to be used at the front end of a casing. The'casing receiving prong can, of course, be adjusted vertically by turning the post 17.

When the wagon is being used at the rear of a casing, the post 17 may be, though not necessarily, removed and instead, a rectangular post 19 is provided. This post or upright 19 has a serrated face for adjustably engaging the serrated inner face 15 of the opening through the body. The post 19 is inserted into the opening to the depth necessary to have the projecting end of sufficient height, after which a movable or removable wedge block 20 is also inserted. As the wedge block 20 moves into the opening, it forces the co-acting toothed or serratedsurfaces of the post and body into interlocking engagement. After the wedge has been inserted to its full depth, a removable pin or bolt 21 is passed through registering openings in the webs 18 and the wedge 20, thus holding the wedge against accidental misplacement. The cut-away portions of the body give ready access to this bolt or pin.

The Wagon is adapted to be drawn or pushed by means of a suitable handle. As shown, the handle is formed. of parallel sections of pipe 23 bolted to the platform by U-bolts 24. The outer ends of'the pipe sections 28 are joined by a cross section 25.

The Wheels 26, of any suitable construction, are carried by the integral axle or studs 8. a

By reference to Fig.5, the usual method of using the invention may be clearly understood. In this figure, A represents the front wagon, B the rear wagon, and C the casing. The frontwagon may be guided by its handle while the rear wagon is pushed. In this Way, the casing is moved without tying or otherwise securing the pipe in place. 7

The integral cast steel construction of the body is stronger and lighter, as Well'as cheaper, than the wooden and metal body heretofore used. The pipe supporting parts may be readily removed, replaced or interchanged, and greater convenience and economy is thereby afforded. The adjustability of the inclined vertical post for use on the rear wagon is also an added feature of conconsiderable importance, in that it enables the upper end of the post to be raised to such a height that when casings of relatively large diameter are being halted, they will clear the ground and wheels, While the post need not be excessively high when smaller casing sections are to be moved. If desired, the wagon can be used at either the front or rear by having both of the posts in position, and properly adjusting them as to height.

Various changes and modifications in the construction shown are within the contemplation of the invention and within the scope of the appended claims.

l/Vhat I claim is:

1. A casing wagon comprising in an integral cast metal structure a platform having a relatively wide forward portion and a relatively narrow rear portion having an opening therein, said structure having a vertical transversely extending plate formed with a reinforced lower edge, axles projecting from theends of, the reinforced portion, a pair of spaced-apart webs extending from the transversely extending plate and under the narrow rearportion, an inclined adjustable post in the opening, and cooperat- 2. A casing wagon comprising a body having wheels for supporting it and having an opening therein which has a serrated Wall, a post adapted to be inserted in the body and having one face thereof arranged to cooperate with the serrated Wall, anda wedge removably inserted in the opening for holding the post in cooperative engagement with the serrated wall'of the opening.

3. A casing wagon comprising a body having wheels for supporting it and having an elongated opening therein, one of the faces of the opening being provided With teeth, a post inserted in said opening having teeth for cooperation with the teeth on said surface, and means for holding the toothed surfaces of the post and opening in cooperative relation to prevent movement of the post. 1

a. A casing wagon comprising a body having wheels for supporting it, a relatively narrow extension on one end of the body which isof less width than the remaining portion of the body and which has an opening therethrough, a serrated wall in the opening, a post inserted in the opening having a face thereon adapted to adjustably engage the serrated face of the opening, a vertically movable wedge in the opening for forcing the post into binding relation with" the ser 'ated surface for holding the post in the position to which it is adjusted, and a transverse pin pressing through the rearward extension and the wedge for holding the wedge in position, the reduced width of the extension giving ready access to the pin.

In testimony whereof I hereunto affix my signature.
